Carotico clinoid foramen and interclinoid bars - A case report

Abstract

We have observed one skull with bilateral carotico clinoid foramen and interclinoid bars formed by fusion of carotico clinoid ligaments between the anterior, middle and posterior clinoid processes. The incidence of the complete type of bilateral carotico clinoid foramen in our study was 1 out of 20 human dry skulls (5%). The bilateral formation of interclinoid bars and carotico-clinoid foramen have high significance due to their rare occurrence. Carotico clinoid foramen may cause changes in the internal carotid artery in clinoid segment which may cause compression of cavernous sinus due to its medial position. Our study provides a guide to neurosurgeons in surgical approaches to prevent fatal complications while performing regional surgeries.
